Metz 45/60 Handle-mount Flash Quench Pin

[jon_erik_lido]

<p>With the release of the RadioPopper JrX system, I am trying to figure out how to build a cable to remotely vary the power of Metz handle-mount flashes. I have a Metz 45 CT-4, but I understand the pin-outs should be the same for all of these models (and maybe more?):</p>

<ul>

<li>Metz 32 CT-4 </li>

<li>Metz 45 CT-3</li>

<li>Metz 45 CT-4</li>

<li>Metz 45 CL-3</li>

<li>Metz 45 CL-4 </li>

<li>Metz 45 CL-4</li>

<li>Metz 60 CT-4</li>

</ul>

<p>The sync cable for these flashes ends in a flat plug with two rows of six electrical contacts (or pins, for lack of a better word.) My question is this:<br>

Which pin on this connector is the quench pin? Any help would be appreciated and would help breathe new life into these trusty, portable and powerful flashes.</p>

<p>As I recall, it actually takes three pins to initiate and quench a Metz, and the logic level is reversed from the Nikon open collector TTL trigger and quench lines. Your best bet is finding an old Metz TTL module Nikon, and then wiring that to your JrX cable, or connecting the Nikon TTL module directly to the radiopopper "cube".</p>
